Richard Erlacher wrote about Z-80 systems from The Digital Group:
and since I don't think they ever came out with a
current (for the
time) FDC, I don't think they ever got an OS running on it.
The originally shipped a single-density FDC for 8-inch drives. It used
some NEC single-density only FDC chip that was *NOT* related in any way
to the uPD765 or the Intel 8271 or 8272. I don't recall the part number,
but it was almost certainly uPD and three digits.
They offered a "Diskmon" OS, and Oasis. I'm not sure that they offered
CP/M, but certainly people ran it.
Later they did a double-density FDC using a more common chip.
